Verifying the nsswitch.conf File
Contents

The nsswitch.conf file is the configuration file
for name-service lookups. This file determines the following information.

The databases within the Solaris environment to use for name-service
lookups

The order in which the databases are to be consulted

Some data services require that you direct “group” lookups
to “files” first. For these data services, change the “group”
line in the nsswitch.conf file so that the “files”
entry is listed first. See the documentation for the data service that you
plan to configure to determine whether you need to change the “group”
line.
